FIELD OF THE INVENTION

This invention generally relates to towed motor vehicle transportationand tools for assisting in towing of vehicles from one location toanother location.

BACKGROUND OF THE INVENTION

The economy of the United States, if not of the world, depends to agreat extent on fleets of large trucks for the distribution of goods,such as foods, consumer products, durable goods, and even industrialequipment. There are many manufacturers of such trucks, which concernprimarily, but are not limited to, class 7 or class 8 over-the-roadtrucks. Once these trucks are manufactured, they require shipment ortransportation either to the carrier or other company for whom the truckwas made, or to a dealer who sells or leases these trucks. The mostobvious method to transport these trucks is by driving them directly totheir destination. This method has disadvantages, at least because eachtruck requires a driver, who must be paid for his or her services andfor whom return transportation must be arranged.

In order to overcome the necessity of a driver for delivering eachtruck, a variety of techniques have been devised to use a first truckthat will carry or tow one or more additional trucks to the desireddestination. One example is shown in U.S. Pat. No. 4,555,214. Thispatent discloses a tow bar that attaches to the fifth wheel of both thetowing vehicle and the towed vehicle. The towed vehicle is towed in arear-ward fashion behind the front vehicle. Using this technique, thetowed vehicle is exposed to the full force of the air that isencountered during the tow. Any aerodynamic surfaces of the towedvehicle will be subjected to reverse stresses, i.e., the wind willimpose loads on the truck at 180° from the direction expected during thedesign of the truck. Thus, the roof cap, side fairings, and anyadditional fairings, such as side and chassis fairings, should be bracedor buttressed for the trip. This adds additional cost to the delivery ofthe truck. In addition, it is not clear that, even using both fifthwheels, the towed truck will have sufficient freedom of movement to beable to rotate slightly during turns.

Another technique is disclosed in U.S. Pat. No. 4,867,468. This patentdiscloses a decking bar that mounts to the truck chassis in front of andabove the front axle of the towed vehicle. The decking bar has arelatively uniform cross section with differently-shaped end portionsand is also relatively short. Using this technique, the towed truck islifted vertically and is not drawn close in a horizontal direction. Inorder to minimize the vertical lift, the decking bar is mounted abovethe front axle of the towed truck, which is then suspended by mountingthe decking bar to the chassis of the towed truck.

Another technique is disclosed in U.S. Pat. No. 5,873,593. This patentdiscloses a piggyback truck transport system. Using this system, a firsttowing truck mounts a second towed truck on its rear portion. The towedtruck is lifted a substantial distance in a vertical direction, puttinga stress on the truck and also putting the combination load at risk forviolating a vertical height limit. The towed truck is lifted asubstantial distance because its front wheels rest on the rear of thetowing truck, thus elevating the towed truck a considerable distance.This height may limit the route which is taken in delivering the trucks.The height may be lessened by removing the front tires of the towedvehicles, which also adds to the delivery expense.

Trucks may also be transported with equipment and a method disclosed inU.S. Pat. No. 6,120,051. This patent discloses a method in which a firsttruck tows a second, rear-facing truck, using a special beam assembly.In this method, a boom saddle is used in conjunction with the fifthwheel of the towing truck and the fifth wheel or a support mount of thetowed vehicle. The special provisions of the boom saddle allow forlateral and vertical movement of the beam assembly. While this methodworks well, it continues to have the disadvantage of towing a vehiclethat faces rear-ward. Thus, the structure of the towed vehicle must bebraced or buttressed during towing, adding to the cost of the tow. Inaddition, the extra wind resistance of the open rear portion of thetruck detracts significantly from fuel economy during a long tow, suchas from a manufacturer to a customer or dealer.

The invention provides better equipment and a better method for towingtrucks. These and other advantages of the invention, as well asadditional inventive features, will be apparent from the description ofthe invention provided herein.

On the contrary, the intent is to cover all alternatives,modifications and equivalents as included within the spirit and scope ofthe invention as defined by the appended claims.

DETAILED DESCRIPTION OF THE PRESENTLY PREFERRED EMBODIMENTS OF THEINVENTION

Embodiments of the present invention are highly useful in transportingtrucks and other vehicles, including new trucks, from one location toanother. While embodiments are most useful in this application, they mayalso be used to transport other vehicles, such as used cars or trucks,from one dealer to another.

As noted above, embodiments of the front tow extended saddle are aimedat safe and economical delivery of vehicles. Accordingly, vehicles towedwith the present embodiments and the present method face forward, theirnormal direction of travel. In this way, there are no additional sideloads or wind loads placed on the vehicles. For instance, many highwayclass 7 and class 8 vehicle have very large aerodynamic cab features,e.g., large fairings designed to deflect the winds encountered in highspeed driving. When a truck with these large surface features is towedwhile facing rear-ward, the beneficial effect of these features is lost.Instead, the aerodynamic features may almost be said to act as athrust-reverser, since the wind is caught in the rear of the cab. Thefeatures and fairings may not be designed for these reversed loads.Thus, in many cases, cabs must be reinforced and buttressed to preventdamage from rear-facing tows at high speed.

In addition, the front tow extended saddle is intended to be aslow-profile as possible, in the sense of minimizing the height of thetowed vehicle. Minimizing the height assures the safest travel overhighways that cross bridges, ramps, and other overpasses. In addition,minimizing the height also minimizes the stress to which the vehicle ortruck is subjected when it is hoisted or lifted into position for thetow. Finally, the front tow extended saddle is intended to function inas economical a manner as possible. The saddle is designed with minimalvertical rise and maximum support of the towed load. One embodiment ispreferably configured so that it may be folded into itself for easiesttransport when it is not being used. This embodiment is preferablyequipped with pivots (sleeves) and locking pins to secure the saddle inplace. Other embodiments may be bolted, welded or otherwise configuredin a permanent configuration that is not able to be folded into itself.

FIGS. 1-2 depict a first embodiment of a front tow extended saddle witha bent configuration that is permanent. Front tow extended saddle 10includes a rear portion 11, a middle portion 12, and a front or forwardportion 13. Rear portion 11 is mounted at a first angle A to middleportion 12, which is mounted at a second angle B to front portion 13.The left and right sides, rails, of each portion are preferably madefrom hollow rectangular tubing, such as 2¾″×6″ hollow structuralsections (HSS), made from ¼″ plate. Other sizes and thicknesses may beused. In this embodiment, rear portion 11 is necessarily wider than theother portions so that rear portion 11 may support the frame rails ofthe towed truck. The sides of rear portion 11 may be secured with crossmembers 18 as shown. Cross members 18 preferably do not interfere withclearances for mounting rear portion 11 to the towed vehicle. The crossmembers may be secured to the left and right sides by welding or otherstructural assembly method. In one embodiment, the rails of rear portion11 are about 48 to 56 inches long and are spaced apart about 30-32inches (inner distance). As may also be seen in FIG. 2, rear and frontportions 11, 13 are parallel to each other, while each of rear, middle,and front portions 11, 12, 13 is on a different plane.

Middle portion 12 is also preferably made from left and right sides ofhollow rectangular tubing, secured to each other by cross member 12 a,preferably by welding. Middle portion 12 may be narrower than rearportion 11, and may be wider than front portion 13. In one embodiment,the rails of middle portion 12 are about 36-40 inches long and arespaced apart to that their outer width (distance on the outer sides ofthe rails) is slightly less than the inner distance between the rails ofthe rear portion.

Front portion 13 is narrower yet than middle section 12, and frontportion 13 includes left and right sides made from hollow structuralsections as described above. The sides are secured to each other bycross members 19. In one embodiment, the rails of front portion 13 areabout 34-38 inches long and are separated such that the outer distancebetween the rails is just less than the inner distance of the rails ofmiddle portion 12. The hollow tubing used for the rails in someembodiments is about 6 inches high and about 2¾ inches wide. In theseembodiments, each successive pair of rails is about 5½ inches, or alittle more clearance for easier handling, narrower or wider than thenext pair. The front portion also includes a mount 14 for securing tothe towing vehicle. In this embodiment, the rear, middle, and frontportions are preferably rigidly assembled to each other by welding.Other methods, such as fasteners, may also be used. Mount 14 includes aking pin for directly mounting to a fifth wheel of the towing vehicle,also allowing for rotation of the extended saddle with respect to thetowing vehicle. A small amount of rotation is desirable in order toallow the towed vehicle to more easily accomplish turns during thetowing procedure.

Rear portion 11 of front tow extended saddle 10 mounts the towed truckusing security assemblies that attach to the towed truck frame and axlesecurity assemblies that attach to the front axle(s) of the towed truck.Accordingly, the left and right side rails of rear portion 11 include aplurality of mounting holes 17. The placement of the holes allows theuser to select the most appropriate pattern for mounting to a particularvehicle. It is understood that the embodiments described herein areapplicable to class 7 and 8 over-the-road trucks, although othervehicles may also be towed using these embodiments. These trucks mayvary in their configurations, i.e., a standard front axle, placed about40″ from the front of the truck, or a set-back axle, 43-46″ from thefront. The axle itself may be a standard axle, with an I-beam crosssection, or may be a Henderickson axle, with a cross section shaped morelike a square. The positions of the lower security assemblies, attachingto the frame, and the axle security assemblies, attaching to the axle,should be horizontally adjustable with respect to rear portion 11 toaccommodate these differences.

Another embodiment of a front tow extended saddle is depicted in FIGS.3-4. In this embodiment, economy of operation is emphasized, because thefront tow extended saddle 30 is made foldable or collapsible byincorporating pivots between the three portions, rear portion 31, middleportion 32, and front portion 33. Rear portion 31 is preferably madefrom hollow structural sections, such as hollow square tubing, the leftand right sides preferably secured with at least one cross member 43,the cross member placed so that it does not interfere with placement ofthe lower security assemblies 36 or axle security assemblies 35, whichmay be similar to those described above. Rear portion 31 mounts the axlesecurity assemblies and lower security assemblies using a plurality ofmounting apertures 37. The security assemblies are preferably mounted torear portion 31 using the apertures and bolts (not shown). There arealso apertures for insertion of locking pins 40.

Middle portion 32 is pivotally secured to rear portion 31 by a pivotingsleeve 38 and is collapsibly secured by locking pins 40. Middle portion32 is pivotally secured to front portion 33 by a pivoting sleeve 39 andis collapsibly secured by locking pins 41. In addition to the pivotingsleeve, each pivot may also include a solid pivot pin within the sleeveto insure the strength of the pivot during towing operations. The fronttow extended saddle is secured by locking pins 40, 41 when the saddle isintended for towing a truck. In the extended position, front and rearportions 33, 31 are preferably parallel, i.e., parallel to each other.

After the tow is complete, saddle 30 may be collapsed or folded byremoving the locking pins and using the pivoting sleeves to fold thesaddle into a much smaller space for a return trip. For instance, if twotrucks are being delivered, one towing and one towed, the front towextended saddle may be returned in a pick-up truck or much smallervehicle, rather than waiting for a return trip by a large truck. Becauseof the much smaller volume of the folded saddle, it is possible toreturn several of the folded saddles in a single return trip, by eithera large truck or a smaller truck capable of handling the load.

For this reason, in a preferred embodiment, the outer width of themiddle portion is less than an inner width of the rear portion, and theouter width of the front portion is less than an inner width of themiddle portion. In other embodiments, there may be only a singlecollapsible or pivoting joint, e.g., there may be an embodiment in whichan inner width of the middle portion is less than an outer width of thefront portion, and there is only a forward pivoting junction between themiddle and front portions. There may also be another embodiment in whichan outer width of the middle portion is less than an inner width of therear portion and there is only a single pivoting point, a rear pivotingjunction between the rear and middle portions.

In the preferred embodiment, the left and right rails of middle portion32 are joined by cross member 46, and the left and right rails include aplurality of apertures for insertion of locking pins 41. Front portion33 includes left and right rails or sides that are secured to each otherwith cross members 44. Front portion 33 also includes mount 34 formounting to the towing vehicle. Mount 44 in this embodiment is an I-beamconfiguration for mounting via J-claws into a saddle mount, such asshown in FIG. 12, and disclosed in U.S. Pat. No. 6,109,642, which ishereby incorporated by reference in its entirety, as though each pageand figure of the '642 patent were set forth in full in this patent. Thesaddle mount is preferably secured to the towing truck and the front towextended saddle is then secured to the saddle mount. The extended fronttow saddle mount may have a fifth wheel pin or a king pin for directinsertion into a fifth wheel, and also allowing for rotation. A smallamount of rotation is desirable in order to allow the towed vehicle tomore easily accomplish turns and maneuvering during the towingprocedure.

The front tow extended saddle is secured to the frame of the truck withpreferably at least four lower security assemblies. As is well known,truck frames include large, long C-shaped steel members, known generallyas channels. The towed truck is mounted to the saddle by two lowersecurity assemblies mounted to a channel on the left side of the truckand two lower security assemblies mounted to a channel on the right sideof the truck. A lower security assembly 16 is depicted in FIGS. 5a and5b . The assembly includes a central structural portion 51, preferably amain hollow structural section 51 and a peripheral flange 52. Flange 52may be mounted to main section 51 by welding and by webs 54. Webs 54 arepreferably sufficiently wide to reinforce the joint and sufficientlynarrow so as not to interfere when a user tightens the nuts around thethreaded portions of two U-bolts 50. Flange 52 includes apertures 53.U-bolts 50 are mounted around the truck channel and are extended throughapertures 53, and are then tightened with the nuts, vertically securingassembly 16 to the rear portion of the front tow extended saddle.Assembly 16 is locked into place horizontally to the rear portion bypins inserted through apertures 57 in the security assembly andapertures 17, 37, in the front tow extended saddles 10, 30, 90. Axlesecurity assemblies 15 are similar in structure to the lower securityassemblies.

In some instances, it is difficult to place a U-bolt around a channel orframe of the vehicle to be towed. This may occur because of lack ofclearance or merely awkward placement of engine components 55 in theengine compartment. In these instances, it may be convenient to useadditional clamps and straight bolts, in place of the normal,straight-forward U-bolts, in addition to a lower security assembly. Onesuch situation is depicted in FIG. 6. Security assembly 60 includes alower frame clamp 61, an optional top frame clamp 62, lower securityassembly 16, first and second bolts 67, 68, and securing nuts 69. Inuse, the user places lower frame clamp 61 around truck frame channel 56.As may be seen more clearly in FIGS. 8a and 8b , assembly 60 willpreferably include two top frame clamps, a single lower frame clamp 61,two first and second bolts 67, 68, with their nuts, and a single lowersecurity assembly 15.

In this embodiment, viewed from the front of the towed vehicle (notshown), lower frame clamp 61 is mounted on the left side of the towedvehicle and the frame clamp is open on the left side, allowing the lowerflange of channel 56 to enter clamp 61. Mounted on the same open, leftside is top frame clamp 62, which is mounted to a convenient structuralhard point, such as a top frame rail flange. Top frame clamp 62 is thensecured to lower frame clamp 61 and lower security assembly 15 by longerbolt 67 and nut 69. On the other side, lower frame clamp 61 is securedto lower security assembly 15 by shorter bolt 68 and nut 69. Theassemblies are preferably mounted so that frame 56 cannot escape lowerframe clamp 61 during the normal stresses and loads encountered during arelatively high-speed tow over a long distance.

Top frame clamp 62 and lower frame clamp 61 are shown in greater detailin FIGS. 7a-7b and FIGS. 8a-8b , and are further explained here. Topclamp shown in FIGS. 7a-7b , is intended to mount to a structural pointand help secure the towed vehicle. Clamp 62 is a single structural piecethat includes a top portion a lower bolt-mounting portion 64, andreinforcing webs 66. There is also an aperture 65 for a bolt to passthrough. Top portion 63 is rounded to form about a 180° curve preferablyhaving a 1½ inch diameter. Lower frame clamp 61, FIGS. 8a-8b , is also asingle structural piece that is preferably, but not necessarily madefrom several components. Mounting plate 81 is made from a rectangularpiece of steel, shorter in the direction of truck travel, as shown, andincludes apertures 82 for bolts. Clamp lower jaw 83 is preferablyintegral with or welded or otherwise secured to mounting plate 81. Lowerjaw 83 is also preferably integral with jaw web 84 and upper jaw 85,leaving area 86 open for engaging a frame member of a truck.

One method of using the front tow extended saddle includes a way topreserve the dimensional integrity of the truck frame elements,typically made with a C-channel cross-section as shown in FIG. 6. Themethod uses an inner frame spacer block assembly 70, as depicted in FIG.7c , to reinforce the truck frame elements. A spacer block 71 ispreferably about 8-10 inches in height, depending on the distancebetween the inner flange surfaces of the channel, and may be about 2inches square to 4 inches square, or may alternately have a rectangularcross section. Other heights and cross sections may be used. The spacerblock is preferably threaded on its inner surface to accommodate anexpansion bolt 75 for adjusting an overall height of the assembly. Bolt75 preferably has an expansion pad 73 on its upper surface to spread theload that is imposed when the spacer block assembly is inserted betweenflanges and tightened.

Optionally, there may also be an expansion pad 72 on the opposite sideof spacer block 71. The spacer block assembly is placed between theflanges and the height adjusted by threading bolt 75 further into or outof block 71. When the height adjustment is correct, expansion adjustmentnut 74 is tightened. One or more inner frame spacer block assemblies maybe used to preserve the dimensional integrity of the truck framecomponents, such as channels. The inner frame spacer block assembly mayalso be used with structural members having cross section of differentshapes, such as I-beams.

It is understood that the front tow extended saddle described herein mayhave many embodiments and may be used in many ways. Another embodimentof a front tow extended saddle is depicted in FIGS. 9 and 10. In thisembodiment, front tow extended saddle 90 is equipped with two offsetaxle security assemblies 97. This embodiment is used for applications inwhich symmetrical axle security members 15, described above, will notfit the truck for which a front tow is desired. Extended saddle 90includes rear portion 91, middle portion 92, and front portion 93.Middle portion 92 is preferably pivotally mounted to rear portion 91 andfront portion 93 by pivot pins 94, 95, as described above.

Leftfender tarp and right fender tarp 290 each are provided with an eyeholeformation so as to be anchored on tube 250. The tarps then pass overtube 260 and extend downward where they are anchored on tube 270. One orboth of the anchor ends of left fender tarp and right fender tarp 290are preferably provided with adjustment means known in the art, such asa sewn bungee cord, so that the tarps can be adjusted, loosened ortightened as necessary to accommodate differences in the towing or towedvehicle, or the length of the saddle.

As shown in FIG. 15, vertical portion 300 comprises left and right sidepanels 310 and 320, rear panel 330 and front panel 340. The side panels310 and 320 are affixed to left and right front rails 212, 214,respectively, by a plurality of huck bolts 350. Huck bolts are known inthe art as a type of bolt that uses special equipment (not shown) toboth insert and remove the bolt, in the removal process shearing off anddestroying the bolt. The use of huck bolts provides a more secureattachment of the vertical assembly to the front member than standardbolts, yet allows for the two assemblies to be detached reasonablyquickly if necessary, unlike welding. Thus, the vertical portion issemi-detachably fixed to the forward portion.

Rear panel 330 is also attached to side panels 310 and 320 through huckbolts, as is front panel 340. Front panel 340 has a lower height thanthe other panels of vertical assembly 300 in order to allow clearancefor forward portion 210.

Two jack assemblies 360 and 362, known in the art, are attached to sidepanels 310 and 320, respectively, through front panel 340 via jackbrackets 370 and 372, respectively, using a combination of huck and/orGrade A bolts. Jack brackets 370 and 372 preferably may includeapertured areas 374 to save on material costs.
